Application filed June 8. 1907. Serial No. 377,984.

To all whom 'it may concern.'

. Be it known that I, CLAnENfJh A. GoU'rY, a rcitizen of the United States, residing at, Springfield, in the county of- Sangamon and State of Illinois, have invIvented a certain new and useful Trolley, of which thc following issuch a-full, clear, and exact description as will enable others skilled in the art to which it appertains to make and use my said invention.

- This invention' relates to trolleys for street cars or the like, andthe purpose is to provide a trolley-harp of improved construction, to provide improved means for mounting `the trolley wheel on the harp, to provide means for limiting the oscillations of the trolley i i,

and to provide means adapted to normally keepl .ne

shown in the annexed drawings, and hereinafter par- `ticularly described and nally'recited in the claims.

Referring to the drawings Figures I and 2 are respectively a side elevation and an end elevation of the trolley. ',Fig. 3"isia partial vertical section on the line 3. 3. of Fig. 2 and Fig. 4 is an enlarged transverse section on 1 he line 4. 4. of Fig. 22

' Similar reference letters and characters designate `like parts in the several views. v

The harp A has a tubular shank A screw-threaded at yboth ends. The upper end of the shank A screws into the harp A. Nuts a and a fit on the lower screwthreaded part of the shank A.

The arch B is la hollow 'casting and has a tubular part b within which the shank A turns, and an internally screw-threaded part b in which the upper end of the trolley-pole ts. The lower end of the harp A turns on 'the upper end of the tubular part b of the arch B.. In

' the upper part of the arch B is a segmental channel b2 accommodatingthe collarD. T Thepgllarjus'rthe lower end ofthe h'Lrp'li and Yis se'cured by a screwed. r"A harp-shaped sprng E is secured on the shank A by a screwe1v and has members e which project through slots ba in the upper part ofthe arch B. The members e'of the spring E are of equal tension and normally act to hold the wheel F in lin'e with the trolley-pole, but under pressureyield sufiiciently to permit the .trolley- :Wheelto'tke any standard curve of the-wire, without running offthewire.

tegral therewith, extends upward within the groove of the wh'epl F and has fiattened parts C against which the flanges f ofthe wheel F strike, on either side., to'prevent excessive oscillation `of the wheel F. The upper end ofthe guardC is about the same height as the cenguard (l mounted on the arch B and preferably inter of the shaft F. The shaft F is supported on the arms of the harp A and the wheel F turns on the shaft F. The shaft F is mounted in the hubs a2 at the upper end of the arms of the harp A and is connected therewith by cotter-pinsf. The wheel F turns on the shaft F. One of the pins f occupies a transverse channella3 in `one of the hubs o.2 and prevents turning oi the shaft.

The 'collar D fitting on the screw-threaded part of the harp A and the screw-threaded shank A screwing into thc lower part of the harp and provided with nuts as shown, serve for accurate adjustment of the harp on the arch at such height that" the point of the guard C will be close enough to prevent the-wire from getting between the point of the guard and the circumference of the wheel F; and the nuts a and al serve to adjust the shank A so that the harp will turn freely on the tubular part b of the arch and yet will not have excessive play. The slots b3 extend downward from the upper end of the tubular part b to admit of inserting the spring E when it is in place on the shank A.

The lower part of the harp A lying upon the upper end of the part b, and the collar D inclosing the upper end of the part b; exclude moisture and dirt from the tubular part b and thereby avoid undue friction and wear of the parts.

In assembling the parts the shank A will be screwed intolthe harp A. The collar'D will then be screwed onto the lower end of the harp A. The spring E will then be secured on the shank A. The shank A with the spring thereon, will be then insertedinto the tubular part b of the arch B and the members e of the spring will pass downward in, and occupy the slots b3, in the arch B. The nuts a and a1 will then be screwed on t0 the lower end of the shank A to give the desired adjustment of the parts. When thecollar D is in place it will be secured by the screw d.

When the parts are assembled as described the upper end ofthe guard C will occupy the groove of the wheel E as shown; the members e will occupy the slots b3 and will b`e ladapted to yield sufliciently to permit the trol- Y ley-wheel F to oscillate to the right or the left to follow the curve of the line wire; the harp A will rest upon the upper end of the tubular part b of the arch; the nuts a and a.1 in place on the shank, will prevent lifting of the harp and the longitudinal opening through the tubular shank A will permit dirt or snow, or other matter likely to interfere with the operation of the wheel,

'to pass freely through the shank A.

Having fully described my invention what I claim as 'new and desire to secure bylLetters Patent is:

part of the' arch, atubular shank screwing into the body of the harp, nuts Afitting on said tubular shank, and a, collarv tting on said harp and inclosing the upper -end of the? tubular part of the arch.

' 2'. In a. tro1ley,' the combination of an arch havinga slotted tubular part and a segmental channel, a harp having a shank, turnabl within the tubular: part of the arch,

and a spring secured on Ache shank of the harp and having members of equal tension fitting in the slots of the tubular part of the a'rch.

3. In a trolley, the combination of slotted tubular part and a segmentaly channel, a guard mounted on said arch, a harpadanted to turn on the tubuan arch having a lar part of vthe arch, af shank adapted for vertcaladjnstment of'the harp relative to the guard on the' shank, a

collar adjustable on the harp and turnable in the channel of the arch, and a spring'securedon the shank of the harp andhaving members of equal tension ttlng in .the slots of the tubular part of the arch.

"In'witness whereof;

I' have lziereuntov subscribed my. name at Sprlggeld, Saugamon county, Illinois, this 15th'
